I'm top 100
But my relationship with the game is love/hate.. I really hate the lag issues, EA's servers are kinda bunk sometimes.
Also, there's something happening which has been called "Dog Tag Lag", where if you knife someone, and if you already have a certain amount of Dog Tags from knifing- say 250-300, your game will lose what feels like 80% of the frame-rate or more- I'd say more, really, but I'm not certain. It's not normal network lag, and usually only happens when you knife someone... but knifing is a big part of the game sometimes... it can be a life-saver, and a way to earn more points.
In order to stop this, and "fix" it, you have to exit the game, and restart.
..So it's kind of broke as of right now.
There was a temporary "fix" to this problem, but since the conquest-mode release, the "DT-Lag" is back.
A couple things people might not like about this game:
1. You're shooting regular soldiers, but they have the strength of the Master Chief... which is counter-intuitive. You gotta pump quite a couple rounds into someone to take them down (AR, sub, LMG). Guys don't go down right away like on COD4.
2. Bullet Lag. Bullets seem to take too long to reach their target. They seem to travel at the speed of paintballs.. but it's almost as if it's a lot of part dependent on the connection to the server. Which brings me to number 3..
3. EA's servers are bunk. Sometimes you will feel like you unloaded a full clip into a guy, and they won't die.
4. If you shoot someone, you call out "enemy soldier!" and the enemy you just shot will have a red dot appear over their head, which can be seen through walls, and on radar. This red dot does not go away for some time, and everyone on you're team knows where that person is for that time, which makes staying alive very difficult, for the enemy (or you, if you're the one being called out).
The red-dots feel like a crutch... They are.
I'm sure there's others... many people complain about this game. I'm included, but I have good and bad times with it.
